11 10K races in September 2026
What the field actually runs
How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Sep 22, 2026.
By the numbers
The September 10K races that stand out on the numbers: the biggest field, and the longest unbroken run of editions.
The busiest weekend in Michigan is September 26 and September 27, with 11 10K races on those two days, and the single busiest day is Saturday, September 26 with 8. Every one of them is on a Saturday or a Sunday.
As early as you can. 1 of these September 10K races already have a price increase on the calendar, and 11 are open for entry right now.
The typical entry is $22, with paid entries running from $10 up to $45. Entry fees climb as race day gets closer, so the same race is usually cheapest the week it opens.
Across the 4 of these September 10K races with published results from past editions, the median finisher ran 1:02:15, and the median winning time was 39:46. So anything under 1:02:15 puts you in the faster half of a typical field. That is the middle of these RunSignup fields, walkers and charity entrants included, not a national average.
The median one finished 241 runners, across the 4 of these September 10K races with published results from past editions. Most are far smaller than the big-city events people picture, which means less crowding at the start and a friendlier field, with a last recorded finisher at 1:48:05.
Yes, one race around Michigan gets you off the pavement: 1 mixes road and trail. Surfaces are not always published, so it is worth checking a specific race before you register.
August and October sit either side of September, which is where most people look next when a date does not fit.
